how to share a movie over e mail thats bigger than 100 megabytes?

Use a service such as Mail Drop or YouSendIt.

you can also share it from dropbox, google drive, ms onedrive or apple cloud drive and share it to the recipient

problem with mails is your mail provider would have a max and so would all recipients and those limits would not necessarily be the same and the recipients limit would never be something you could alter..
